√144 + 3√8 + 15/15 =

12 + 3√ [4 *2] + 1 =

13 + 3 * √4 * √2 =

13 + 3* 2 * √2 =

13 + 6√2

I assume this is

x/7 = x - 36 multiply both sides by 7

x = 7x - 252 subtract 7x from both sides

-6x = -252 divide both sides by -6

x = 42

2cos^2(x)-7cos(x)-4=0 factor this as :

(2cos(x) + 1 ) (cos(x) - 4) = 0

Setting the second factor to 0, we have :

cos(x) - 4 = 0 add 4 to both sides

cos(x) = 4 which has no solution

Setting the first factor to 0, we have

2cos(x) + 1 = 0 subtract 1 from both sides

2cos(x) = -1 divide both side by 2

cos(x) = -1/2 and this occurs at 2pi/3 and at 4pi/3 radians on the requested interval

If you mean what i think you mean, which is that the points are too far for the paper or graph, then you should use a larger scale or a break in the graph. Both work just fine.

You're on a CALCULATOR website. How lazy can you be? But if you don't know how to do it without a calulator, then its like this:

208763/(4/5)=208763*(4/5)=The answer=167010.4

D. 2p - 3 = 8

Proof .....add 3 to both sides

2p = 11 divide both sides by 2

p = 11/2 = 5.5

It weighed 5.5 lbs yesterday......twice that = 11 lbs.......and 3 lbs less than that = 8 lbs

https://www.mathsisfun.com/ is also a very good website for pretty much any type of math.

For help, khan academy is just the place.

First convert to slope-intercept form:

y=mx+b

m=slope

b=y-intercept

Y-3=3(x+1)

y-3=3x+3

+3 +3

y=3x+6

1. m=3

2. (-1,3):

Point slope form (the form the equation was in):

y-y₁=m(x-x₁)

y-(3)=3(x-(-1))

x₁=-1

y₁=3

(-1,3)

3. y=3x+6, figured that out abovve

4. b=6

5.3x-y=-6:

y=3x+6

-6-y -6-y

-6=3x-y

6.-2

Graph it. It's pretty simple. If you can't, the formula is:

-(b/m) (Actually, I don't know if there is a formula, but this will still work.)

b=6

m=3

-(6/3)=-2

If you took the time to read all of that, you should have at least a basic understanding of your homework.

i have a trigometry question, "find each measure to the nearest degree or whole number." theres a right triangle, the oppisite side is "w" adjacent is "v" and hypotenuse is "13" the angle next to the 90 degree is 61 degree, please help.

Sin(61)=w/13

0.8746197=w/13

w=13 x 0.8746197=11.37- the Opposite side, or 11

The second angle=90 - 61=29 degrees

13^2=11^2 + v^2

169=121 + v^2

v^2=169 - 121

v^2=48

v=sqrt(48) =~7

There's a calculator here, just punch that expression and hit the enter key. But if you aren't allowed to use a calculator, then it would look like:

233

4465

*596

xxxxxx

xxxxx0

xxxx00

xxxxxxx

That's what it should look like, but I put x both because I don't feel like figuring it out and beause if you can't use the calculator, I can't do it for you.
